Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 313,033,315, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 313,033,315 | |
| -1 | -313,033,315 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 313,033,315.
Example:
1 x 313,033,315 = 313,033,315
and
-1 x -313,033,315 = 313,033,315
Notice both answers equal 313,033,315
With that explanation out of the way, let's continue. Next, we take the number 313,033,315 and divide it by 2:
313,033,315 ÷ 2 = 156,516,657.5
If the quotient is a whole number, then 2 and 156,516,657.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 313,033,315 | |
| -1 | -313,033,315 |
Now, we try dividing 313,033,315 by 3:
313,033,315 ÷ 3 = 104,344,438.3333
If the quotient is a whole number, then 3 and 104,344,438.3333 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 313,033,315 | |
| -1 | -313,033,315 |
Let's try dividing by 4:
313,033,315 ÷ 4 = 78,258,328.75
If the quotient is a whole number, then 4 and 78,258,328.75 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 313,033,315 | |
| -1 | 313,033,315 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 49 | 107 | 245 | 535 | 749 | 3,745 | 5,243 | 11,941 | 26,215 | 59,705 | 83,587 | 417,935 | 585,109 | 1,277,687 | 2,925,545 | 6,388,435 | 8,943,809 | 44,719,045 | 62,606,663 | 313,033,315 |
| -1 | -5 | -7 | -35 | -49 | -107 | -245 | -535 | -749 | -3,745 | -5,243 | -11,941 | -26,215 | -59,705 | -83,587 | -417,935 | -585,109 | -1,277,687 | -2,925,545 | -6,388,435 | -8,943,809 | -44,719,045 | -62,606,663 | -313,033,315 |
